RESUMEN

OBJECTIVES: To investigate the role of cytoreductive radical prostatectomy in addition to standard of care for patients with newly diagnosed metastatic prostate cancer. MATERIALS AND METHODS: This multicentre, prospective study included asymptomatic patients from 2014 to 2018 (NCT02138721). Cytoreductive radical prostatectomy was offered to all fit patients with resectable tumours, resulting in 40 patients. Standard of care was administered to 40 patients who were ineligible or unwilling to undergo surgery. The primary endpoint was castration resistant cancer-free survival at the time point of ≥50% events. The secondary endpoint was local event-free survival. Kaplan-Meier and Cox regression analyses with propensity-score analysis were applied. RESULTS: After a median (quartiles) follow-up of 35 (24-47) months, 42 patients became castration-resistant or died. The median castration resistant cancer-free survival was 53 (95% confidence interval [CI] 14-92) vs 21 (95% CI 15-27) months for cytoreductive radical prostatectomy compared to standard of care (P = 0.017). The 3-year estimates for local event-free survival were 83% (95% CI 71-95) vs 59% (95% CI 51-67) for cytoreductive radical prostatectomy compared to standard of care (P = 0.012). However, treatment group showed no significance in the multivariable models for castration resistant cancer-free survival (P = 0.5) or local event-free survival (P = 0.3), adjusted for propensity-score analysis. Complications were similar to the non-metastatic setting. Patients undergoing surgery were younger, with lower baseline prostate-specific antigen levels, alkaline phosphatase levels and metastatic burden. CONCLUSION: The present LoMP study was unable to show a difference between the two inclusion groups regarding castration resistant cancer-free survival for asymptomatic patients with newly diagnosed metastatic prostate cancer. These results validate previous evidence that, in well-selected and informed patients, cytoreductive radical prostatectomy is feasible and safe, with corresponding continence rates compared to the non-metastatic, high-risk setting. Whether cytoreductive radical prostatectomy could be a valuable option to achieve good local palliation needs to be further researched. Overall, the role of cytoreductive radical prostatectomy needs to be further explored in randomized studies to correct for potential bias.

RESUMEN

PURPOSE: Surgical innovation is necessary to ensure continued improvement in patient care. However, several challenges unique to the surgical craft are encountered during the development and validation of such new technology. This article highlights some of these challenges and gives an overview of existing solutions. METHODS: A Pubmed review was performed about the "introduction of new technology" to identify challenges. Cross-referencing was used to explore the possible solutions per challenge. RESULTS: Several characteristics of the surgical craft itself limit our ability to establish randomised controlled trials and hence provide clear categorical evidence. Existing certification bodies for new technology often use unstructured regulations and allow fast-track bypassing systems. Consequently the IDEAL framework (innovation, development, exploration, assessment, long-term follow-up) proposes an objective scientific approach whilst defining stakeholder responsibilities. The selection of which new modality to implement is heavily influenced by third parties unrelated to the best patient outcomes and thus professional organisations can aid in this decision-making. Appropriate training of surgeons and their teams until proficiency is achieved is essential prior to credentialling. Finally long-term surveillance of outcomes in the form of registries is an increasing responsibility of the urological community to maintain our role in directing the adoption or rejection of these innovations. CONCLUSION: Urological innovation is a dynamic and challenging process. Increasing efforts are identified within the urological community to render the process more reliable and transparent.

RESUMEN

PURPOSE: To evaluate local recurrence in younger men treated with low-dose-rate (LDR) 125I brachytherapy (BT) for localized prostate cancer. PATIENTS AND METHODS: A total of 192 patients (≤65-years-old) were treated with LDR 125I-BT ± hormone therapy. Local failure was defined as any prostate-specific antigen (PSA) rise leading to salvage treatment or biochemical failure according to the Phoenix definition. A bounce was defined as a rise in the nadir of ≥0.2 ng/mL followed by spontaneous return. Proportions were compared using Fisher's exact tests; continuous variables using the unpaired t-test or its non-parametric equivalent. Cox proportional hazards models were applied for multivariable survival analysis. RESULTS: Median follow-up was 66 months. The 5­year local recurrence-free survival was 96.1%. Biopsy-proven local recurrence developed in 13 patients, 4 had a Phoenix-defined recurrence at the last follow-up. Androgen deprivation therapy was started in 1 patient without proven recurrence. Univariable risk factors for local recurrence were: at least 50% positive biopsies, intermediate risk, treatment with neoadjuvant hormone therapy, low preimplantation volume receiving 100% of the prescribed dose, and no bounce development. Hormone-naïve patients not attaining a PSA value <0.5 ng/mL during follow-up also had a higher risk of local recurrences. Cox regression demonstrated that the variables "at least 50% positive biopsies" and "bounce" significantly impacted local failure (hazard ratio, HR 1.02 and 11.59, respectively). A bounce developed in 70 patients (36%). Younger patients and those treated with a lower activity per volume had a higher chance of developing a bounce in the Cox model (HR 0.99 and 0.04, respectively). CONCLUSION: For younger men, LDR BT is a valid primary curative treatment option in low-risk and is to consider in intermediate-risk localized prostate cancer.

RESUMEN

OBJECTIVES: To describe the anatomical patterns of prostate cancer (PCa) recurrence after primary therapy and to investigate if patients with low-volume disease have a better prognosis as compared with their counterparts. MATERIALS AND METHODS: Patients eligible for an 18-F choline positron-emission tomography (PET)-computed tomography (CT) were enrolled in a prospective cohort study. Eligible patients had asymptomatic biochemical recurrence after primary PCa treatment and testosterone levels >50 ng/mL. The number of lesions was counted per scan. Patients with isolated local recurrence (LR) or with ≤3 metastases (with or without LR) were considered to have low-volume disease and patients with >3 metastases to have high-volume disease. Descriptive statistics were used to report recurrences. Cox regression analysis was used to investigate the influence of prognostic variables on the time to developing castration-resistant PCa (CRPC). RESULTS: In 208 patients, 625 sites of recurrence were detected in the lymph nodes (N1/M1a: 30%), the bone (18%), the prostate (bed; 11%), viscera (4%), or a combination of any of the previous (37%). In total, 153 patients (74%) had low-volume recurrence and 55 patients (26%) had high-volume recurrence. The 3-year CRPC-free survival rate for the whole cohort was 79% (95% confidence interval 43-55), 88% for low-volume recurrences and 50% for high-volume recurrences (P < 0.001). Longer PSA doubling time at time of recurrence and low-volume disease were associated with a longer time to CRPC. CONCLUSIONS: Three out of four patients with PCa with a 18-F choline PET-CT-detected recurrence have low-volume disease, potentially amenable to local therapy. Patients with low-volume disease have a better prognosis as compared with their counterparts. Lymph node recurrence was the most dominant failure pattern.

RESUMEN

BACKGROUND: Metastases-directed therapy (MDT) with surgery or stereotactic body radiotherapy (SBRT) is emerging as a new treatment option for prostate cancer (PCa) patients with a limited number of metastases (≤3) at recurrence - so called "oligometastases". One of the goals of this approach is to delay the start of palliative androgen deprivation therapy (ADT), with its negative impact on quality of life. However, the lack of a control group, selection bias and the use of adjuvant androgen deprivation therapy prevent strong conclusions from published studies.The aim of this multicenter randomized phase II trial is to assess the impact of MTD on the start of palliative ADT compared to patients undergoing active surveillance. METHODS/DESIGN: Patients with an oligometastatic recurrence, diagnosed on choline PET/CT after local treatment with curative intent, will be randomised in a 1:1 ratio between arm A: active surveillance only and arm B: MTD followed by active surveillance. Patients will be stratified according to the location of metastasis (node vs. bone metastases) and PSA doubling time (≤3 vs. > 3 months). Both surgery and SBRT are allowed as MDT. Active surveillance means 3-monthly PSA testing and re-imaging at PSA progression. The primary endpoint is ADT-free survival. ADT will be started in both arms at time of polymetastatic disease (>3 metastatic lesions), local progression or symptoms. The secondary endpoints include progression-free survival, quality of life, toxicity and prostate-cancer specific survival. DISCUSSION: This is the first randomized phase 2 trial assessing the possibility of deferring palliative ADT with MDT in oligometastatic PCa recurrence. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT01558427.

RESUMEN

What's known on the subject? and What does the study add? Very few comparative studies to date evaluate the results of treatment options for prostate cancer using the most sensitive measurement tools. PSA has been identified as the most sensitive tool for measuring treatment effectiveness. To date, comprehensive unbiased reviews of all the current literature are limited for prostate cancer. This is the first large scale comprehensive review of the literature comparing risk stratified patients by treatment option and with long-term follow-up. The results of the studies are weighted, respecting the impact of larger studies on overall results. The study identified a lack of uniformity in reporting results amongst institutions and centres. A large number of studies have been conducted on the primary therapy of prostate cancer but very few randomized controlled trials have been conducted. The comparison of outcomes from individual studies involving surgery (radical prostatectomy or robotic radical prostatectomy), external beam radiation (EBRT) (conformal, intensity modulated radiotherapy, protons), brachytherapy, cryotherapy or high intensity focused ultrasound remains problematic due to the non-uniformity of reporting results and the use of varied disease outcome endpoints. Technical advances in these treatments have also made long-term comparisons difficult. The Prostate Cancer Results Study Group was formed to evaluate the comparative effectiveness of prostate cancer treatments. This international group conducted a comprehensive literature review to identify all studies involving treatment of localized prostate cancer published during 2000-2010. Over 18,000 papers were identified and a further selection was made based on the following key criteria: minimum/median follow-up of 5 years; stratification into low-, intermediate- and high-risk groups; clinical and pathological staging; accepted standard definitions for prostate-specific antigen failure; minimum patient number of 100 in each risk group (50 for high-risk group). A statistical analysis (standard deviational ellipse) of the study outcomes suggested that, in terms of biochemical-free progression, brachytherapy provides superior outcome in patients with low-risk disease. For intermediate-risk disease, the combination of EBRT and brachytherapy appears equivalent to brachytherapy alone. For high-risk patients, combination therapies involving EBRT and brachytherapy plus or minus androgen deprivation therapy appear superior to more localized treatments such as seed implant alone, surgery alone or EBRT. It is anticipated that the study will assist physicians and patients in selecting treatment for men with newly diagnosed prostate cancer.

RESUMEN

BACKGROUND: In Belgium, bladder cancer is the fifth most common cancer in males (5.2%) and the sixth most frequent cause of death from cancer in males (3.8%). Previous epidemiological studies have consistently reported that selenium concentrations were inversely associated with the risk of bladder cancer. This suggests that selenium may also be suitable for chemoprevention of recurrence. METHOD: The SELEBLAT study opened in September 2009 and is still recruiting all patients with non-invasive transitional cell carcinoma of the bladder on TURB operation in 15 Belgian hospitals. Recruitment progress can be monitored live at http://www.seleblat.org. Patients are randomly assigned to selenium yeast (200 µg/day) supplementation for 3 years or matching placebo, in addition to standard care. The objective is to determine the effect of selenium on the recurrence of bladder cancer. Randomization is stratified by treatment centre. A computerized algorithm randomly assigns the patients to a treatment arm. All study personnel and participants are blinded to treatment assignment for the duration of the study. DESIGN: The SELEnium and BLAdder cancer Trial (SELEBLAT) is a phase III randomized, placebo-controlled, academic, double-blind superior trial. DISCUSSION: This is the first report on a selenium randomized trial in bladder cancer patients. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00729287.

RESUMEN

BACKGROUND: We did a randomised phase 3 trial assessing the benefit of addition of long-term androgen suppression with a luteinising-hormone-releasing hormone (LHRH) agonist to external irradiation in patients with prostate cancer with high metastatic risk. In this report, we present the 10-year results. METHODS: For this open-label randomised trial, eligible patients were younger than 80 years and had newly diagnosed histologically proven T1-2 prostatic adenocarcinoma with WHO histological grade 3 or T3-4 prostatic adenocarcinoma of any histological grade, and a WHO performance status of 0-2. Patients were randomly assigned (1:1) to receive radiotherapy alone or radiotherapy plus immediate androgen suppression. Treatment allocation was open label and used a minimisation algorithm with institution, clinical stage of the disease, results of pelvic-lymph-node dissection, and irradiation fields extension as minimisation factors. Patients were irradiated externally, once a day, 5 days a week, for 7 weeks to a total dose of 50 Gy to the whole pelvis, with an additional 20 Gy to the prostate and seminal vesicles. The LHRH agonist, goserelin acetate (3·6 mg subcutaneously every 4 weeks), was started on the first day of irradiation and continued for 3 years; cyproterone acetate (50 mg orally three times a day) was given for 1 month starting a week before the first goserelin injection. The primary endpoint was clinical disease-free survival. Analysis was by intention to treat. The trial is registered at ClinicalTrials.gov, number NCT00849082. FINDINGS: Between May 22, 1987, and Oct 31, 1995, 415 patients were randomly assigned to treatment groups and were included in the analysis (208 radiotherapy alone, 207 combined treatment). Median follow-up was 9·1 years (IQR 5·1-12·6). 10-year clinical disease-free survival was 22·7% (95% CI 16·3-29·7) in the radiotherapy-alone group and 47·7% (39·0-56·0) in the combined treatment group (hazard ratio [HR] 0·42, 95% CI 0·33-0·55, p<0·0001). 10-year overall survival was 39·8% (95% CI 31·9-47·5) in patients receiving radiotherapy alone and 58·1% (49·2-66·0) in those allocated combined treatment (HR 0·60, 95% CI 0·45-0·80, p=0·0004), and 10-year prostate-cancer mortality was 30·4% (95% CI 23·2-37·5) and 10·3% (5·1-15·4), respectively (HR 0·38, 95% CI 0·24-0·60, p<0·0001). No significant difference in cardiovascular mortality was noted between treatment groups both in patients who had cardiovascular problems at study entry (eight of 53 patients in the combined treatment group had a cardiovascular-related cause of death vs 11 of 63 in the radiotherapy group; p=0·60) and in those who did not (14 of 154 vs six of 145; p=0·25). Two fractures were reported in patients allocated combined treatment. INTERPRETATION: In patients with prostate cancer with high metastatic risk, immediate androgen suppression with an LHRH agonist given during and for 3 years after external irradiation improves 10-year disease-free and overall survival without increasing late cardiovascular toxicity.

RESUMEN

Introduction and Objective: Definitive inclusion of renal mass biopsy (RMB) in small renal mass (SRM) diagnostic algorithm remains controversial. We assessed incidence and accuracy of RMB in SRMs in the CROES Renal Mass registry and the influence of preoperative RMB on perioperative complications after SRM nephron-sparing surgery (NSS). Materials and Methods: "ad hoc" description of incidence of preoperative RMB and characteristics of SRM cases with and without RMB. Accuracy of RMB was calculated in the SRM subcohort that received extirpative treatment and complication rate after NSS compared to between the two groups. Continuous variables were compared using t-test; categorical variables were compared using the chi-square test. K-statistics was used to analyze agreement between the biopsy histology and surgical pathology. Logistic regression was used to assess the association between RMB and NSS complications. All tests were two sided, and p-values <0.05 were considered statistically significant. Results: The rate of preoperative RMB in SRMs was 11.6% (175/1597) in Europe and the United States. RMB patients were more likely to have hypertension (p < 0.04), be on dialysis (p < 0.024), or smokers (p = 0.005), with multiple/bilateral tumors (0.008 and 0.010) and previous other malignancy (p = 0.021). They underwent radical nephrectomy more frequently than non-RMB group (p = 0.034). RMB was nondiagnostic in 16 cases (9%). Accuracy of RMB in distinguishing malignant from benign was 89.5%. Agreement between biopsy and final surgical pathology was 93% for malignant vs benign tumors (kappa = 0.655). Upstaging to pT3a occurred more frequently in the RMB group (12.6% vs 6.25% [p = 0.022]). Complication rate in renal mass-NSS subcohort was 15.8%, not statistically different between RMB and non-RMB groups. On logistic regression analysis, RMB was not associated with increased risk of postoperative complication after NSS (OR: 0.9, 95% CI: 0.43-1.89). Conclusion: The practice of RMB in SRM is still scarce despite high accuracy and concordance with final pathology. RMB does not seem to increase complication rate after NSS.

RESUMEN

The optimal management of patients with oligorecurrent prostate cancer (PCa) is unknown. There is growing interest in metastasis-directed therapy (MDT) for this population. The objective was to assess cost-utility from a Belgian healthcare payer's perspective of MDT and delayed androgen deprivation therapy (ADT) in comparison with surveillance and delayed ADT, and with immediate ADT. A Markov decision-analytic trial-based model was developed, projecting the results over a 5-year time horizon with one-month cycles. Clinical data were derived from the STOMP trial and literature. Treatment costs were derived from official government documents. Probabilistic sensitivity analyses showed that MDT is cost-effective compared to surveillance (ICER: €8393/quality adjusted life year (QALY)) and immediate ADT (dominant strategy). The ICER is most sensitive to utilities in the different health states and the first month MDT cost. At a willingness-to-pay threshold of €40,000 per QALY, the cost of the first month MDT should not exceed €8136 to be cost-effective compared to surveillance. The Markov-model suggests that MDT for oligorecurrent PCa is potentially cost-effective in comparison with surveillance and delayed ADT, and in comparison with immediate ADT.

RESUMEN

Purpose Retrospective studies suggest that metastasis-directed therapy (MDT) for oligorecurrent prostate cancer (PCa) improves progression-free survival. We aimed to assess the benefit of MDT in a randomized phase II trial. Patients and Methods In this multicenter, randomized, phase II study, patients with asymptomatic PCa were eligible if they had had a biochemical recurrence after primary PCa treatment with curative intent, three or fewer extracranial metastatic lesions on choline positron emission tomography-computed tomography, and serum testosterone levels > 50 ng/mL. Patients were randomly assigned (1:1) to either surveillance or MDT of all detected lesions (surgery or stereotactic body radiotherapy). Surveillance was performed with prostate-specific antigen (PSA) follow-up every 3 months, with repeated imaging at PSA progression or clinical suspicion for progression. Random assignment was balanced dynamically on the basis of two factors: PSA doubling time (≤ 3 v > 3 months) and nodal versus non-nodal metastases. The primary end point was androgen deprivation therapy (ADT)-free survival. ADT was started at symptomatic progression, progression to more than three metastases, or local progression of known metastases. Results Between August 2012 and August 2015, 62 patients were enrolled. At a median follow-up time of 3 years (interquartile range, 2.3-3.75 years), the median ADT-free survival was 13 months (80% CI, 12 to 17 months) for the surveillance group and 21 months (80% CI, 14 to 29 months) for the MDT group (hazard ratio, 0.60 [80% CI, 0.40 to 0.90]; log-rank P = .11). Quality of life was similar between arms at baseline and remained comparable at 3-month and 1-year follow-up. Six patients developed grade 1 toxicity in the MDT arm. No grade 2 to 5 toxicity was observed. Conclusion ADT-free survival was longer with MDT than with surveillance alone for oligorecurrent PCa, suggesting that MDT should be explored further in phase III trials.

RESUMEN

OBJECTIVE: To prospectively evaluate patients with newly diagnosed metastatic prostate cancer in the context of the LoMP trial (which investigates the role of cytoreductive radical prostatectomy [cRP] in addition to standard of care [SoC]) and to provide a preliminary analysis of patient's characteristics, safety of cRP, and early local symptoms. PATIENTS AND METHODS: cRP was performed in asymptomatic patients with a resectable tumor and who were fit to undergo surgery (group A, n = 17). Only SoC was administered to patients with metastatic prostate cancer ineligible or unwilling to undergo cRP (group B, n = 29). At 3 months, surgical complications related to cRP and local symptoms for both groups were evaluated. RESULTS: Median operation time, blood loss, and hospital stay for cRP were 215 minutes (150-290), 250 mL (100-900), and 4 days (2-7), respectively. Respectively 5 (29.4%) and 2 (11.8%) patients suffered grades 1 and 2 complications within 3 months postoperatively. When compared with Group B, patients in group A were younger (64 vs 72 years, P = .005), had lower initial prostate-specific antigen (15.9 vs 156 µg/L, P = .002), and less high-volume metastatic disease (5.9% vs 69%, P <.001). At 3 months, 5 (29.4%) patients in group A reported stress urinary incontinence without any further local symptoms. In group B, respectively 2 (6.8%), 11 (37.9%), and 2 (6.8%) patients suffered urge incontinence, obstructive voiding needing medical intervention, and ureteric obstruction. CONCLUSION: In a group of well-selected patients, cRP is safe. These patients have more favorable characteristics compared with patients treated with only SoC. If only SoC can be offered, patients are at risk to suffer from local symptoms.

RESUMEN

BACKGROUND: Androgen deprivation therapy has been associated with worsened body image in prostate cancer patients. Body image and physical presentation changes were investigated in patients receiving a gonadotropin-releasing hormone analogue (triptorelin) as part of treatment for locally advanced or metastatic prostate cancer. OBJECTIVE: The aim was to evaluate the changes in self-perception of the body and to assess the relationship of these changes over a period of 2 years in men treated with triptorelin as primary therapy for advanced or locally advanced prostate cancer. METHODS: Data were collected for 2 years in accordance with routine clinical practice. Body image was assessed using the body image scale (BIS). Patient body mass index (BMI) and waist circumference were also measured. RESULTS: BIS and BMI data for both baseline and a least one post-baseline visit were available for 98 of the 145 patients enrolled. The median change in BIS score for patients assessed around 12 or 24 months after baseline and at the last observation was zero, indicating no body image deterioration in at least half of patients. Statistically significant BIS score increases were detected in assessments around 6, 12 and 18 months, but not after 2 years, indicating some patients experienced body image deterioration at some point during treatment. Changes in BMI from baseline were modest and generally not statistically significant. Waist circumference increased during the study (mean ± standard deviation increase of 1.00 ± 5.01 cm at the last observation). Positive correlations were determined between increases in BIS score and both BMI and waist circumference (r = 0.235 and 0.267, respectively; p = 0.020 and 0.008) at the last observation for all patients, as well as during the second year of the study. CONCLUSIONS: Most patients did not experience clinically meaningful worsening of body image perception during the study. BMI and waist circumference had a modest impact on body image during study year 2.

RESUMEN

BACKGROUND: In Belgium, bladder cancer (BC) is the fifth most common cancer in men. The per-patient lifetime cost is high. Previous epidemiological studies have consistently reported that selenium concentrations were inversely associated with the risk of BC. We therefore hypothesised that selenium may be suitable for chemoprevention of recurrence of BC. METHOD: The Selenium and Bladder Cancer Trial (SELEBLAT) was an academic phase III placebo-controlled, double-blind, randomised clinical trial designed to determine the effect of selenium on recurrence of non-invasive urothelial carcinoma conducted in 14 Belgian hospitals. Patients were randomly assigned by a computer program to oral selenium yeast 200 µg once a day or placebo for three years, in addition to standard care. All study personnel and participants were blinded to treatment assignment for the duration of the study. All randomised patients were included in the intention to treat (ITT) and safety analyses. Per protocol analyses (PPAs) included all patients in the study three months after start date. RESULTS: Between September 18, 2009 and April 18, 2013, 151 and 141 patients were randomised in the selenium and placebo group. Patients were followed until December 31, 2015. The ITT analysis resulted in 43 (28%; 95% CI, 0.21-0.35) and 45 (32%; 95% CI, 0.24-0.40) recurrences in the selenium and placebo group. The hazard ratio (HR) was 0.85 (95% CI, 0.56-1.29; p = 0.44) while the HR for the PPA resulted in 42 and 39 (28%; 95% CI, 0.20-0.35) recurrences in the selenium and placebo group (HR = 0.96 [95% CI, 0.62-1.48]; p = 0.93). CONCLUSION: Selenium supplementation does not lower the probability of recurrence in BC patients.

RESUMEN

INTRODUCTION: This large multicenter study aimed to assess the impact of the use of multimedia tools on the duration and the quality of the conversation between healthcare providers (urologists, radiotherapists and nurses) and their patients. METHODS: 30 urological centers in Belgium used either videos or other instructive tools in their consultation with prostate cancer patients. Each consultation was evaluated for duration and quality using a visual analog scale. RESULTS: In total, 905 patient visits were evaluated: 447 without and 458 with video support. During consultations with video support, an average of 2.3 videos was shown. Video support was judged to be practical and to improve the quality of consultations, without loss of time, regardless of patient age or stage of disease management (p > 0.05). CONCLUSION: Healthcare providers indicate that the use of videos improved patient comprehension about prostate cancer, as well as the quality information exchange, without increasing consultation time. The use of video material was feasible in daily practice, and was easy to understand, relevant and culturally appropriate, even for the most elderly men. Multimedia education also helped to empower men to actively participate in their healthcare and treatment discussions. FUNDING: Ipsen NV.

RESUMEN

BACKGROUND: Locoregional lymph node metastasis is an important prognostic factor in patients with bladder cancer. Multimodal treatment, depending on preoperative stage, may improve survival. The standard imaging modalities for staging (computed tomography [CT] or magnetic resonance imaging [MRI]) have an accuracy range of 70-90% for lymph node staging. A more accurate preoperative diagnostic test could improve survival rates even more. OBJECTIVE: To determine whether the use of 2-deoxy-2 [F] fluoro-D-glucose (FDG) positron emission tomography (PET) in combination with CT (FDG-PET/CT) can increase the reliability of preoperative lymph node staging in patients with nonmetastatic invasive bladder cancer (T2 or higher, M0) or recurrent high-risk superficial disease (T1G3 with or without Tis, M0). DESIGN, SETTING, AND PARTICIPANTS: Fifty-one patients underwent a preoperative FDG-PET/CT between April 2004 and December 2007. Independent of the result for lymph node status, all patients underwent a radical cystectomy and an extended lymphadenectomy. The FDG-PET/CT and CT results were compared with the definitive pathologic results. MEASUREMENTS: Among the 51 patients, 13 patients had metastatically involved locoregional lymph nodes, diagnosed on histopathology. In six patients, these nodes demonstrated increased FDG uptake on PET. In seven patients, PET/CT did not diagnose the positive lymph nodes. PET/CT was false positive in one patient. RESULTS AND LIMITATIONS: For the diagnosis of node-positive disease, the accuracy, the sensitivity, and the specificity of FDG-PET/CT were 84%, 46%, and 97%, respectively. When analysing the results of CT alone, there was accuracy of 80%, sensitivity of 46%, and specificity of 92%. The use of FDG-PET/CT is hampered by technical limitations. CONCLUSIONS: We found no advantage for combined FDG-PET/CT over CT alone for lymph node staging of invasive bladder cancer or recurrent high-risk superficial disease.

RESUMEN

OBJECTIVES: To evaluate the technical and oncologic feasibility of laparoscopic nephroureterectomy for upper urinary tract transitional cell carcinoma. METHODS: A retrospective survey of 100 patients, treated with laparoscopic nephroureterectomy in 10 Belgian centres, was performed. Most procedures were performed transperitoneally. The distal ureter was managed by open surgery in 55 patients and laparoscopically in 45 patients. The mean follow-up was 20 mo. RESULTS: Mean operation time was 192 min and mean blood loss 234 ml. The conversion rate was 7%. Important postoperative complications were seen in 9%. Pathologic staging was pTa in 31 patients, pT1 in 23, pT2 in 12, pT3 in 33, and pT4 in 1, concomittant pTis in 3. Pathologic grade was G1 in 24 patients, G2 in 28, and G3 in 48. Negative surgical margins were obtained in all but one patient. Twenty-five patients developed progressive disease (24%) at a mean postoperative time of 9 mo (local recurrence in 8%, metastases in 11%, both in 5%). Progression was 0% for pTa, 17% for pT1, 17% for pT2, 51% for pT3, and 100% for pT4. Cancer-specific survival was 100% for pTa, 86% for pT1, 100% for pT2, 77% for pT3, and 0% for pT4. CONCLUSION: Laparoscopic nephroureterectomy appears to be a technically and oncologically feasible operation. To prevent tumour seeding, one should avoid opening the urinary tract and should extract the specimen with an intact organ bag. The high local recurrence rate in this study probably reflects the high percentage of high-grade and high-stage tumours in this study.
